    Having trouble VE tuning, Logs and Tune posted

    I'm having trouble tuning my VE table,
    Gen 4 5.3
    Manual Trans

    I logged and did the multiply by percent a couple times, but it seems to be getting worse according to the log.

    Take a look and see, I must be missing something in my tune.

    Are you sure the MAF is failed, you need to log the MAF sensor status to know for sure.

    The settings are right for SD yet. You want them at 2hz and 1hz and the MAF dtc's must be on MIL on first error for the 3 MAF dtc's. Pretty much P0103 needs to be present for SD.

    Remove the MAF channels when logging to prevent skewed data.

    Are you using fuel trims or a wideband to tune the VVE tables?
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    ill double check what I have the codes set as, I'm thinking I habe them on no error report.

    I'm using fuel trims for now, trying to get it right under 4000 rpm
